Description

Description: TECHNICAL FIELD The present invention relates to a fertilizer application device mounted on an agricultural work machine, and more particularly to a fertilizer application device configured to prevent clogging of fertilizer.

[Prior art and its problems]

In this type of conventional technique, a fertilizer tank, a fertilizer feeding device, an air tank, etc. are provided at a position far from the fertilizer application position and fertilizer is transferred to the fertilizer application position by a long fertilizer application pipe. Therefore, the fertilizer application pipes are arranged almost horizontally, and the fertilizer clogging frequently occurs.

[Means for solving problems]

In order to solve the above problems, the present invention provides a fertilizer tank (1), a fertilizer feeding section (2), and a fertilizer transfer section (3) above the fertilizer application position (1).
And an air tank (5) for collecting the compressed air from the blower (4), and the fertilizer fed from the fertilizer tank (1) at the fertilizer feeding section (2) is moved downward by the compressed air in the air tank (5). Fertilization position (a)
It is a fertilizer applicator for agricultural work machines that is provided for forced transfer.

〔The invention's effect〕

According to the present invention, by the above technical means, the length of the fertilizer transfer portion that connects the fertilizer feeding portion and the fertilizer application position is short, and the fertilizer can be arranged steeply. Since the fertilizer is forcibly transferred downward by the compressed air, it is possible to prevent the fertilizer transfer part from being clogged with fertilizer, and a good fertilization work can be performed.

〔Example〕

(6) is a riding type vehicle body, and a link mechanism (7)
A four-row seedling planting machine (9) is attached so as to be vertically movable via a hydraulic device (8).

The riding type vehicle body (6) has a traveling mission case (1
0) is provided, and the engine frame (11) is extended toward the front from the traveling mission case (10).
The engine (12) is mounted on the (11). In addition, the chain cases (13L) and (13R) are extended diagonally rearward and downward from both left and right rear portions of the traveling mission case (10), and the left and right drive wheels (13L) and (13R) are attached to the tips of the chain cases (13L) and (13R). 14L) and (14R) are provided.

(15L) and (15R) are driving front wheels for left and right steering, (16) is a steering wheel, and (17) is a cockpit.

The four-row seedling planting machine (9) includes a planting section transmission case (18), a left and right sub-transmission case (19L) extending rearward from the rear end of the planting section transmission case (18) in a cantilever manner. ) ・ (19R), the left and right sub-transmission cases (19L) ・ (19R) are attached to the left and right sides of the rear end of each, and can be reciprocally moved up and down, one share from the bottom of the seedling tank (22) described below. Seedling planting device (21) for splitting and planting seedlings in the field ...
Seedling tank (22), which is supported by the planting part transmission case (18) and reciprocates left and right, and the rear part of the planting part transmission case (18), the left and right sub-transmission cases (19L), and (19R), respectively. A central ground leveling float that is pivotally supported and its front part is mounted to move up and down by a link mechanism (23c), (23L), (23R), and the above-mentioned seedling planting device (21) lands the soil surface for planting seedlings. (24a) ・ Left and right leveling float
It is composed of (24L) and (24R).

(5) is an air tank, which is provided to collect the compressed air sent through the blower pipe (25) by the blower (4) driven by the engine (12), and the left and right auxiliary transmission cases The left and right auxiliary transmission cases (19L) and (19R) are attached to the left and right auxiliary transmission cases (19L) and (19R) by the left and right support columns (26L) and (26R) extending upward from the respective upper surfaces of the (19L) and (19R).

(1) is a fertilizer tank, which is fixed to the air tank (5) through supporting metal fittings (27), and has a feeding roll (28) for feeding a fixed amount of fertilizer at a lower portion thereof. Feeding part
(2) is constantly provided.

(29) is a grooving tool composed of left and right side plates, and the central leveling float (24c) is arranged so that the seedling planting device (21) can be placed laterally to the planting position for planting seedlings in the field. It is fixed to the left and right leveling floats (24L) and (24R).

(3) is a fertilizer transfer section consisting of a synthetic resin tube,
It is provided to guide the fertilizer fed from the fertilizer feeding section (2) between the both side plates of the groove making tool (29). The middle part of the fertilizer transfer part (3) and the air tank (5) are in communication with each other by the air guide pipe (30), and the compressed air in the air tank (5) causes the fertilizer transfer part (3) to be in the lower part. The fertilizer is forcibly sent to the grooving tool (29).

Next, explaining the operation of the above example, start the engine (12), put seedlings in the seedling tank (22), fertilizer tank (1)
When granular fertilizer is put into the plant and each part is driven to move the machine forward, the seedling planting work and fertilization work are carried out at the same time.In particular, the fertilizer feeding part (2) is fed from the fertilizer tank (1) by a fixed amount. The granular fertilizer to be fed out is the fertilizer transfer section installed at a steep slope.
Passing through (3), still forced by the compressed air from inside the air tank (5), into the groove formed in the field with the groove making tool (29) provided on the side of the seedling planting position. Since it is transferred, good fertilization work can be performed without causing trouble such as clogging of fertilizer.

In addition, the air tank (5) has left and right support columns (26L) and (26R) on top of the left and right auxiliary transmission cases (19L) and (19R) that are cantilevered from the planting section transmission case (18). Since it is fixed via the left and right auxiliary transmission cases (19L) and (19R), which are extended in a cantilever manner.
It becomes a reinforcing member that connects the middle part of the
(18) and left and right vice traditional cases (19L) and (19R) and left and right support columns (26
L) ・ (26R) and air tank (5) form a robust quadrilateral framework, so there is no need to make the left and right auxiliary transmission cases (19L) ・ (19R) particularly sturdy. 9) can be made lighter.

In addition, each fertilizer tank is attached to the air tank (5) that is long in the left-right direction.
(1) ... and each fertilizer feeding part (2) ... are unitized to be easily attached to and detached from the seedling planting machine (9), and the fertilizer tank (1) ... and feeding part (2) ) ... No special support member is required, and the structure is simple.

In addition, although the above-mentioned embodiment explained the seedling planting machine,
The present invention may be applied to other agricultural working machines such as a seeder.
